ther object is to provide an ,improved `arrangement for applying the power to the l@ mechanism so that the latter may, if desired,

be efficiently and quickly reversed. With these as well as other objects in view, the invention resides in the novel features of Jconstruction as more fully hereinafter set forth.

rlhe high density compress has the base 1 which is formed of the spaced pairs of columns 2 with each pair connected at their upper ends by the cross bars 3, preferably integral therewith. 4 is the upper platen of the high density compress mounted upon the base and having the laterally extending portions 5 above the cross bars 3 and the depending portion 6 extending between these cross bars and serving as a spacer. 7 are tie rods extending transversely through the cross bars and the depending portion for securing the parts together'. 8 is the lower platen below the upper platen and suitably guided by the columns 2 and adapted to be raised and lowered by means including the toggle levers 9 and the reduction gearing 10, this reduction gearing being above and mounted upon the upper platen 4. p

' 11 are the. side platens which are pivotally mounted at their lower ends upon the hinge members 12 rigidly secured to the columns 2. These side platens are actuated by toggle levers comprising the upper'and lower levers 13 and 14, respectively, pivotally connected 192e; semi No. 353,492.

to eachother with the upper levers pivotally connected at 1'5 to the swinging edges of the sidefplatens and the lower levers pivotally mountedupon the shaftsl, whichare spaced outwardly from and extend parallel tothe side platens. The levers 13 and 14 are adapt ed to be in substantial alignment when the side platens Vare in-closed position so that the force( exerted upon these levers for closing the side platens tends to laterally separate the shafts 16. For supporting thesershaft's there are the tiel rods 17 connectedto the shafts and extending transversely of the ends of the compress and' mounted in the brackets 18 u porrthecolumns 2.' There are also the tension rods 19 connectedat their Ylower ends to the ,shafts 16 and at their lupper ends to the'uu'pper portion of the base,v 1.1 In de teil; the uppefrortonsl Qfthese tension rods extendbetween the` bifurcations 20 upon and preferably integral with the columns2 are threadedbeyond the bifurcationsforenl gageinent by the 21 which abut `the washers 22 having roundedlower faces engaging correspondingly rounded uppery faces upon the bifurcations. By adjusting the nutsupon" the rods, the shafts 16 may be raisedor lowered to provide `for proper closing of the sidefplatens. Y y' Y i The lowerlevers 14 are provided'with the dependingl arms 23, thelower endsfof which are pivotally connected to'V theouter ends" of.- theinaiaj 24.; rte time; gaat of these 'links are' pivo'tally connected tothe outer ends of the liiikfs"`2v5 by thegpins V26, which pinsextend 'transverse-ly? through the, cross heads 27 guided b'y the brackets 28'. Specifically, the sides of these cross heads are slotted forV engagement withthe plateis29 upon'the brackets.V 30 'and`31 are'revoluble gears to the' formero'f which the inner'end ofa'link'25 is" pivotaflly conn'ect'edby-the 32 and tothe latteriof which theV inneirendfy ofthe other v link 25 `is pivotallyl connected `bythe pin'33." These gears'arein axial alignmer'itA and-the pins`32 and ,33,1 the platesl29"fuponrthe brack#v ets V28, and thc/pins connecting vthe Y arms 23 toftheplinks l24C arey so arranged that when the Aside platens 11 are in closed position the links 24' and 25 are in alignment andthe planes passing through the axes of the pins 26 and 32 and 33 pass through the axes of the gears to facilitate holding the toggle levers in operative position maintaining the side platens in closed position.

For theV purpose of locating the levers 13 and 14 in substantial alignment when the side platens are in closed position the mechanism for operating these togglelevers is made adjustable to take care of inaccuracies either in the sizes of the parts or in their ymounting and also to take care of wear. Asrshown, the links 24 are adjustable, each link comprising the inner part 34 and the outer part 35. The part 34 has its inner end pivotally connected to the cooperating link 25, while the part 35 is in the nature of a yoke having its arms pivotally connected to the cooperating arm 23 and its base apertured for the passage of the outer endof the part 34. Suitable nuts 36 are threaded upon the part 34 and abut the baseof the part 35 to adjustably secure the part 34 to the part 35. With this adjustable arrangement, it will be seen that the levers 13 and 14 can be made to assume substantially axial alignment when the side platens are in closed position and furthermore that this substantial alignment can be maintainedirrespective of the wear or of the adjustment of the shafts 16 to which the toggle levers are connected. v

The revoluble gears are mounted upon the shafts 37 and 38, respectively, which are journaled in the frame members 39 and '40, respectively, below y and rigidly secured to the hinged members 12. These revoluble ear members are engaged by pinions 41 an 42, respectively, which are ixedly secured upon the shaft 43 journaled in the frame members '39 and 40. lThis shaft has iiXedly secured thereto the worm gear 44, which meshes with the wormv45 upon the'shaft 46. This shaft is adapted to be normally rotated in one direction by means of the electric motor 47 which is adapted to be connected to the shaft by means of the belt 48 vand the clutch 49. 50 is a'brake drum Xed upon the shaft 46 between the worm 45 and the clutch 49 and adapted to be engaged by suitable braking mechanism. With this arrangement the motor 47 may be continuously driven and the operation of the side platens controlled by throwing the clutch in or out of operative engagement. If some obstruction is presented while closing the side platens the clutch may be readilyy thrown out of engagement to allow the side platens to open under gravity. Also when the side platens are in closed position the clutch may be thrown out of engagement while the bale is being compressed upon upward movement of the lower platen. Further, when the levers 13 and 14 have been moved olf center after the compressing operation, the clutch may be thrown out of engagement to allow the side platens to lower under gravity.

What we claim as our invention is:

1. In a high density compress, a side platen and means for actuating the same including toggle levers connected to said side platen, a revoluble member, a link connected to said toggle levers, a second link pivotally connected to said first mentioned link andrev-v second link pivotally connected to said irst mentioned link and to said .revoluble member, and a guide for the pivot between said links arranged so that when the toggle levers are in extended posit-ion and the side platen is in closed position Vthe plane extending through the axes of the pivotal connections of said second link extends adjacent to the aXis of said revoluble member.

In testimony whereof we aliix our signature.
